such a tragic situation? I would not venture to say that large scale migrations are like­ ly to bring about, all by themselves, a harmonious distribution ~f population. It must be recognized, nevertheless, that economists and geographers alike are ready to admit that this problem, and the problem of economic pressure which derives therefrom, cannot be satisfactorily settled unless a well devised policy of regulation is set up, in order to bring all manpower available closer to the natural resources of wealth. It follows that in the present days the migration policy of any given country has to be considered in the light of international co-operation. This planetary vision of all great human problems is a welcome sign of our times.
